Specification of Letters Patent.

Patented Dec. 4, 1906.

To all whom it rrtay concern:

Be it known that I, WILLIE D. WIIITNEY, a citizenof the Uuitcdslatos, I'esidingnt Holley, in the county of Orleans and State of New York, have invented a new and useful Washing-Machine, of which the following is a specification.

This invention relates to washing-niacinnos of that class in which the clothes are sulfijected to a combined rubbing and squeezing action with a view of removing dirt in a thorough and expeditious manner.

Th e principal object of the invention is to provide a machine of this ty e in which the clothes to bc washed are paced in a con tainer, usually in the form of a tub, that receives oscillatory movement in a horizontal plane, this movement being transmitted in the form of vertical reciprocatory movement to an auxiliary rubbing member arranged Within the tub.

A further object of the invention is to provide a washing-machine in which the upper rubbing and compressing disk receives a positive vertical movement to an extent proportionate to the are through which the tub oscillates.

A still further object of the invention is to provide a machine of this character in which the u per rubbing-disk may be readily removed to crluit the insertion and removal of the clot es.

A still further object of the invention is to provide a machine of this type in which the disk-actuatin cam is carried by the tub and the latteris he d at aconstaut level during its oscillatory movement, so that the operation of the machine is rendercdlcss laborious than in machines where it is necessary for the oporator to move both the tub and its contents vertically.

With these and other objects lll view, as will more fully hereinafter appear, the inven tion consists in certain nove features of con- Struction and arrangement of arts heroinafter fully described, illustrated In the accompanying drawings, and particularly pointed out in the appended claims, It being understood that various changes in the form, proportions, size, and minor details of the structure may he made without departing from the spirit or sacrificing any of the advantages of the invention. i

In the accompanying drawings, Figure l is a perspective view of a washing-machine constructcd in accordance with the invention. Fig. 2 is a detail perspective view of the tubcarricd cam for actuating the upper ruhhin disk. l i 3, 4, and 5 are detail views, hereinafter re erred to, of a modified construction of the mechanism for transmitting movement from the cam to the upper rubbingdislr. Fig. 6 is a sectional elevation of a washingmaclune, illustrating a slight modification in which the tub-carried cam is arranged to un )nrt positive movement to the up or disk in 0th directions. Fig. 7 is a detai perspective view of the cam shown in Fig. 6. ig. 8 is an elevation, artly in section, illustrating a further modification in which the cam is arranged slightly above the bottom of the tub. view of the cam shown in Fig. 8. Fig. 10 is an elevation of a washing-machine, illustrating a still further modification of the invention in which two separate cams are employed at. or near the upper edge of the tub, thc'ends of the cams being spaced to permit the rollers to readily pass from contact therewith when the upper ruhbing-disl is to he raised. Fig. 11 is a side elevation looking from the direc tionindicated at the arrow in Fig. 10. Fi 12 is a front elevation of a machine in whidll a single cam is employed for actuating a pivotally-niounted rubbing-disk. Fig. 13 is a side elevation of the structure shown in Fig. 12.

Similar numerals of reference are employed to indicate corresponding arts throughout the several figures of the diawings.

lhc base of the machine is formed of a plurality of le s or standards 10, that are connected at t Ieir up 101' ends by a metallic spider-frame 11, said irame having a central opening for the reception of a vertical spindle 12, carrying a disk or spider 13, that is firmly secured to the bottom of the clothescontainer or tub 14, the tub being so mounted as to permit free oscillatory movement in a horizontal plane, and toaccom lish this the operator may grasp the edge 0 the tub. The tub may be of any ordinar construction, and its bottom is preferab y rovided with rubbing bars or members 15, w ich may be arranged radially, as shown.

To the tub is secured a cam 16, and said cam may be a single or a double cam and may be secured to the bottom of the tub or Fig. 9 is a detail perspective at any point between the lower and upper edges thereof.

Extending from the central spider 11 are two pairs 0 diametrically-opposed arms 17, these being connected at their outer ends by a cross-bar 18, that is arranged for the reception and support of a spring-containing casing 19. Extending within the casing are two vertical arms 20, which pass through openings in the bars 18 and at their lower ends are provided with inwardly-extending brackets 21, on the inner ends of which are mounted antifriction-rollers 22, that bear against the lower face of the cam. Each of these arms 20 is provided with a collar 23, between which and the upper face of the bar 18 is arranged a helical compression-spring 24, that tends to elevate the arm 20.

T he up )er ends of the arm 20 are bent inward, and to the end of one of them is hinged a cross-bar 26, that is adapted to engage with the inturned end of the other arm, any suitable locking device, such as a slidable sleeve 27, being arranged to inclose the interlappin ends of the arm and bar for the purpose 0 preventing upward movement 0 said bar. At the central portion of the bar 26 is arrangedia non-circular opening for the passage 0 a non-circular bar 31), which carries at its lower end a rubbing and squeezing disk 31, the lower face of which is preferably pro vided with a rubbing-bar 32, and in this disk are formed perforations 33 for the passage of the water.

The disk 31 may be vertically adjustable in accordance with the quantity of clothes to be washed and when so adjusted may be locked by means of a suitable set-screw 35, extending through a thread ed opening formed in the cross-bar 26.

In the construction illustrated in Fig. l the cam-ring 16 is firmly secured to the lower edge of the tub, and said cam-ring has its lower face divided into two active cams the meetin points of which are indicated at as. The rollers 2'2 are held against these camfaces by the springs 24, the construction bein" such that the rollers in moving upward wi l tend naturally to assume a position midway between the points a: of the cams.

The clothes to be washed, a quantity of water, and a suitable detergent are placed in the tub, and disk 31 is adjusted down on top of the clothes and then looked in place b the screw 35. The operator then procee s to impart an oscillatory movement in a horizontal plane to said tub. As the points a: of the cam move around in the direction of the rollers 22 said rollers will be moved down, and this movement will be imparted against the resistance offered by the springs 24 to the arms 20 and the upper rubbing-disk 31, said disk being moved down to an extent proportioned to the are of oscillation of the tub, and as this are is wholly under the control of the operator the degree of pressure exerted on the clothes may be increased or diminished at will.

The operation is not laborious, owing to the fact that as the higher or,rather,lowcr points of the cam near the rollers '22 the springs are placed under stress and in expanding to reassume their initial position will tend to turn the tub in the reverse direction, so that the tub receives an initial start and the move ment may be completed by hand It is found in practice that if the disk 31 is not lowered to such an extent as to press very forcibly on the clothes the tub may be started into motion and will oscillate back and forth a number of times without the exertion of further force, so that the work of the operator is comparatively light.

In some instances it may be preferred to employ a live roller, and in this case the bracket 21* is substituted for the bracket 21 as shown in Figs. 3, 4, and 5. This bracket 21' comprises an arm 60, that extends under the edge of the tub and carries at its inner end an elongated arcuate loop (31, arranged to form a pair of parallel rails or flanges 6), that are disposed on curved lines struck from the axis of movement of the tub. These rails or flanges receive the journals 64 65 of a live roller 66, that bears against the lower 9 face of the cam, and the peripheries of the roller and journals are arranged on lines that radiate from the vertical axis of the tub, so that the movement of the tub over the roller may be accomplished without und ue friction, the rollers riding freely against the cam and their journals moving freely on the rails or flanges 62.

In the construction illustrated in Figs 6 and 7 the cam 16 is a double cam-that is to say, ithas two faces that bear against opposite sides of the roller, so that the move' ment imparted thereto will be positive in both directions instead of being positive in one direction and spring-actuated in the other, as in Fig. 1. In this case the upper and lower rings which form the cam are connected together by webs 68, that are formed integral with the cam-rings, and from the upper ring project lugs 69. The construction otherwise remains the same as that shown in Fig, l, with the exception that the tubular members 19 merely form guides for the arms 20.

In the construction shown in Figs. 8 and 9 the cam 16' is formed of upper and lower rings, connected at their ends by webs 68, and said cams are further connected by inwardly-extending yoke-shaped plates 70, that are provided with suitable openings 71 for the assage of screws or other fastening devices y which the cam-ring is secured to the tub. These plates are extended inward in order to avoid interference with the rollers 22 or their spindles, and in this case the spindles or carrying-arms 21 of the rollers are in the form of straight bars, threaded at their outer ends and extending through vertical slots formed in the guiding-casings 19, the threaded portion of the arm being screwed in suitable openings formed at the lower ends of the vertically-movable arms 20.

In Figs IOand 11 is illustrated a still l'ur thcr modification of the invention, in which the cams are arranged close to the upper edge of the frame. In this instance the cams 16 are double cams and are separated from each other at their ends, so that by turning the tub beyond the normal limit of oscillatory movement the cams may be moved beyond the rollers, and the latter being then free will permit the raising of the upper rubbing-disk in itscarrying-frame. in this construction the main-lraimspider is provided with a laterallyextended arm 37, which at a point beyond the side of the tub is bent upward in a vertical plane, and to its upper end is pivoted an arm 73 This arm 73 extends inward to about the plane of the vertical axis of the tub and at that point is provided with a pair of arms 74, Fig. 10, that extend at right angles to the arm 73, all of said arms 73 and 74 radiating from a centrally-disposed hub member 75, that is provided with a central opening or the passage of the 'bar 30, which supports the upper rubbin -disk 31. The outer ends of the arms 74 are out downward and inward and carry the antifrietionrollers 22, the latter extending between the rings of the double cam I6, as shown. In this construction the tub may be oscillated in the usual manner, and the movement is transmitted to the upper rubbingdisk through 'therollers 22 and arms 74, the upper disk, however, moving in the are of a circle the center of which is at the folcrum-point of the arm 73. 'hen it is desired to raise the upper rubbing-disk in order to remove the clothes from the tub, the latter is moved beyond its normal limit or until the rollers are free from the ends of the cams, after which the free arms 74 and 73 may be swun upward, carrying with them the upper rubbing-disk to the position shown in dotted lines in Fig. I 1.

In the construction shown in Figs. 1; and 13 a single cam 16 is employed, while the arm 17" (shown in Fi s. l0 and It) isrctained. To the up or end of this arm 17 is pivoted an arm 73, t iat extends diametrically across the plane of the tub, its free end being bent downward and inward and carrying a single antifriction-roller 22, which enters between the two rings of the actuating-cam 16. In this case the single cam may be ell'eetivctv employed for imparting movement in a vertical plane to the up er rubbing-disk, and when the tub is mover beyond its normal limit of oscillatory movement the cam passes beyond the roller, leaving the latter free, so that the arm 73, together with the upper rubbingdislr, may heswum upward to the dotted-line position llltlStItlbMTlll l ig. 13.
